ASM 磁盘组的的scrip
之前经常用如下方式进行查询：
步骤 1 以oracle用户登录系统。
步骤 2 执行如下命令改变ORACLE_SID环境变量。
$ export ORACLE_SID=+ASM1【1或者2】
需要通过ps -ef|grep ASM 确认实例名称
步骤 3 执行如下命令进入ASM管理状态。
$ asmcmd -p
步骤 4 执行如下命令查看存储空间。
$ ASMCMD> lsdg
[@more@]
最近发现如下的简易方式：
export ORACLE_SID=+ASM【1或者2】
需要通过ps -ef|grep ASM 确认实例名称

SELECT SUBSTR(D.NAME,1,16) AS ASMDISK, D.MOUNT_STATUS, D.STATE,D.PATH,
DG.NAME AS DISKGROUP FROM V$ASM_DISKGROUP DG, V$ASM_DISK D
WHERE DG.GROUP_NUMBER = D.GROUP_NUMBER;
sample 1:
1) As Oracle or Grid OS user, run the next commands on each node (if ASMLIB API is used):
# /etc/init.d/oracleasm scandisks #(only this command needs to be executed as root user)
$> id
$> /etc/init.d/oracleasm listdisks
$> /etc/init.d/oracleasm querydisk <each disk from previous output>
Note: All the disks must be visible from each node.
2) Confirm the disks are visible (I/O) at OS level (as oracle or grid OS user) from each node:
$> ls -l <disk name>
$> dd if=<raw/character or block partition device in question> of=/dev/null count=100 bs=8192
Example:
$> dd if=/dev/raw/raw1 of=/dev/null count=100 bs=8192 # raw device
$> dd if=/dev/oracleasm/disks/PRODA07 of=/dev/null count=100 bs=8192 # ASMLIB device
$> dd if=/dev/rdsk/c1t3d0s6 of=/dev/null count=100 bs=8192 # raw device
3) Verify that kfed can read on the candidate disk(s) at OS level (as oracle or grid OS user) from each node:
Example:
$> kfed read /dev/oracleasm/disks/PRODA07
$> kfed read /dev/rdsk/c1t3d0s6
4) Create a new temporary diskgroup:
5) Check if the diskgroup is created and mounted:
6) If so, then manually mount it on the other ASM instance(s):
SQL> SELECT STATE, NAME FROM V$ASM_DISKGROUP;
7) If the previous steps had success and the TEST diskgroup can be successfully mounted (on each ASM instance), then drop the TEST diskgroup as follow:
SQL> DROP DISKGROUP TEST; --(from the ASM instance, which the diskgroup is still mounted).
8) Then the candidate disk is ready to be added to the desired diskgroup:

How To Gather & Backup ASM/ACFS Metadata In A Formatted Manner version 10.1, 10.2, 11.1, 11.2, 12.1 and 12.2? (文档 ID 470211.1)
Solution
Script #1 (Generic ASM metadata):
Script #2 (ASM Files & ASM Alias):
Script #3 (ASM Full Path Alias Directory):
Script #4 (ASMCMD commands to gather complementary metadata information):
Example Output (Script #1):
Example Output (Script #3):
Example Output (Script #4):
References
APPLIES TO:
Oracle Database - Enterprise Edition - Version 10.1.0.2 to 12.2.0.1 [Release 10.1 to 12.2]
Exadata Database Machine X2-2 Hardware - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.
***Checked for relevance on 30-Apr-2010***
GOAL
You can use the SQLPLUS “SET MARKUP HTML ON” to generate a formatted report from the existing ASM metadata and also using ASMCMD commands to gather complementary metadata information, which can be used as well as an ASM metadata backup or as a report for Oracle Support to troubleshot ASM issues.

SOLUTION
1) Connect to your ASM instance(s) and execute the first 3 scripts below (on each node if this is RAC configuration).
2) Also, execute the script #4 (located below) through ASMCMD to gather complementary metadata information (on each node if this is RAC configuration).
Note 1: Scripts #1, #2 & #3 could report the <<< ORA-01219: database not open: queries allowed on fixed tables/views only >>> error on some specific queries, due to some V$ASM_* performance views are only present on early ASM releases, therefore this errors can be ignored depending the ASM release.
Note: 2: This is the same case with the Script # 4 (ASMCMD commands), which could not interpret some ASMCMD commands, due to the some commands/options are not present on early releases.

This is an intended behavior implemented in 10.2. File modification date is always rounded off to nearest hour in past, update is performed only if previous timestamp is different from current value after rounding off. 只显示整数时间点，可能与实际时间有一小时的差异

###This will activate any interface which does not have HOTPLUG=no set, regardless of the ONBOOT setting.

######kfed issue
KFED – ERROR!!! could not initialize the diag context
ERROR!!! could not initialize the diag context
uid=503(grid) gid=501(oinstall) groups=501(oinstall),504(asmadmin),505(asmoper),506(asmdba)
-rwxrwxrwx 1 grid oinstall 2097152000 Jul 5 22:14 /u02/oradata/asm_disk0
CAUSE
kfed executable will need create a directory for its own trace files under <GridHome>/log/diag/asmtool and/or <GridBase>/diag/asmtool. If kfed firstly was used as root user, this directory - <GridHome>/log/diag/asmtool and/or <GridBase>/diag/asmtoolis created as root. The following kfed run by other than root user will not be able to create a directory under <GridHome>/log/diag/asmtool.
drwxrwxrwx 2 grid oinstall 4096 Jul 5 15:29 asm
drwxr-xr-x 3 root root 4096 Jul 6 11:17 asmtool << This directory is owned by root and there is no write permissin for other users.

或者:
in grid:
truss kfed
statx("/c/igfs/oracleapp/diag", 0x0FFFFFFFFFFFD070, 176, 0) Err#2 ENOENT
mkdir("/c/igfs/oracleapp/diag", 0775) Err#13 EACCES
kioctl(1, 22528, 0x0000000000000000, 0x0000000000000000) = 0
ERROR!!! could not initialize the diag context
kwrite(1, " E R R O R ! ! ! c o u".., 48) = 48
SOLUTION
Change the owner for <GridHome>/log/diag/asmtool and/or <GridBase>/diag/asmtool ( based on your GridHome version ) directory as grid user.
# chown grid:oinstall $ORACLE_HOME/log/diag/asmtool
And as grid user, the following command will show the correct kfed output.
$kfed read /u02/oradata/asm_disk0 | more
kfbh.endian: 1 ; 0x000: 0x01
kfbh.hard: 130 ; 0x001: 0x82

ASMLIB可能带来的缺点:
- 对于多路径设备(multipathing)需要在/etc/sysconfig/oracleasm-_dev_oracleasm配置文件中设置ORACLEASM_SCANORDER及ORACLEASM_SCANEXCLUDE，以便ASMLIB能找到正确的设备文件，具体可以参考Metalink Note<How To Setup ASM & ASMLIB On Native Linux Multipath Mapper disks? [ID 602952.1]>
- 因为ASM INSTANCE使用ASMLIB提供的asm disk，所以增加了额外的层面
- 每次Linux Kernel更新，都需要替换新的ASMLIB包
- 增加了因人为错误造成宕机downtime的可能
- 使用ASMLIB意味着要花费更多时间去创建和维护
- 因为ASMLIB的存在，可能引入更多的bug，这是我们最不想看到的
- 使用ASMLIB创建的disk，其disk header并不会和普通的asm disk header有什么不同，仅仅是在头部多出了ASMLIB的属性空间。
结论:
我个人的观点是尽可能不要使用ASMLIB，当然这不是DBA个人所能决定的事情。另一方面这取决于个人习惯，在rhel 4的早期发行版本中没有提供udev这样的设备管理服务，这导致在rhel 4中大量的ASM+RAC组合的系统使用ASMLIB , 经网友指出udev 作为kernel 2.6的新特性被引入，在rhel4的初始版本中就已经加入了udev绑定服务，但是在rhel4时代实际udev的使用并不广泛(In Linux 2.6, a new feature was introduced to simplify device management and hot plug capabilities. This feature is called udev and is a standard package in RHEL4 or Oracle
Enterprise Linux 4 (OEL4) as well as Novell’s SLES9 and SLES10.)。如果是在RHEL/OEL 5中那么你已经有充分的理由利用udev而放弃ASMLIB。
ASM Specific
- Use ASMLib for ease of management and for increased performance provided by the ASMLib Async I/O driver.
Note: For RedHat Enterprise Linux 6 (beginning with 6.4) the kernel driver package 'kmod-oracleasm' is available directly from RedHat, and can be installed from the "RHEL Server Supplementary (v. 6 64-bit x86_64)" channel on RedHat Network (RHN). Updates to this module will be provided by RedHat. Additional information may be found in Document 1089399.1. - When using ASMLib in a multipath environment ensure that ASMLib has been configured properly such that the multipath device is used for access to the devices. This is achieved by editing the /etc/sysconfig/oracleasm configuration file and modifying the ORACLEASM_SCANORDER to include a valid prefix entry from /proc/partitions (e.g. "dm","emcpower"). A common misconfiguration is to have ORACLEASM_SCANORDER" set to "/dev/mapper/". "/dev/mapper: are aliases which will NOT exist in /proc/partitions. See Document 602952.1 for details.
- If you are NOT or are unable to use ASMLib please refer to Document 357472.1 for guidance on how to configure UDEV and/or Device Mapper to manage Clusterware and ASM devices.
- On Linux 7 systems using FCOE and ASMLib, ensure FCOE service starts before ASMLib. See Document 2065945.1 and Document 2043733.1 for additional details.
